Abstract
Summary
better understanding of wave fields that propagate in the near-surface and true underground medium, help to study the complex mountainous prestack migration imaging method. However, topography poses a problem for finite difference method. The present studies of the free-surface condition are concerned with the more general isotropic cases. This paper extends the image method from the existing elastic/viscoelastic isotropic media model to anisotropic medium model. This new method is simple to implement in conventional staggered finite difference schemes, is computationally efficient and enables modeling of highly irregular topography.
